INTERNAL coMBus rIon Application filed October 22, 1927, Serial R0.228,028, Renewed. April 7,

This invention relates to internal combustion engines and it is anobject of the invention to provide a driving connection between thepistons and crank shaft through the medium of a turning cross headconstructed and assembled in a manner to substantially eliminate theliability or" dead center and which assures maximum of eliiciency ofeach of the pistons throughout the entire stroke thereof.

It is also an object of the invention to pro vide a motor of this kindwherein is avoided piston slam against the walls of the cylinders with aresultant elimination of vibration and a material reduction in wear ofthe pistons and cylinders.

Another object of the invention is to provide a motor constructed in amanner whereby substantially twice the power is obtained withsubstantially the same amount of fuel as required by internal combustionengines now generally in use.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved internalcombustion engine whereby certain important advantages are attained. andthe device rendered simpler, less expensive and otherwise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein 7 Figure 1 is a fragmentary view partly in verticalsection and partly in elevation illustrating an internal combustionengine constructed in accordance with an embodiment of my invention;

Figure 2 is a view partly in elevation and partly in section of thestructure as illustrated in Figure 1 at substantially a quarter turnwith respect thereto; and Figure 3 is a view in top plan of the crosshead unapplied.

As disclosed in the accompanying draw ings, B denotes an engine blockprovided with the cylinders 1 in each of which is arranged a piston 2.-Each ot the pistons 2 has pivotally engaged therewith, as at 3 an endportion of a piston rod 4. This, piston rod elis disposed toward theopen end of the cylinder 1 and is hingedly connected, as at 5, witha-turning crosshead C. i i

r The cross head G comprises a castbocly member 6, the central portionofwhich being provided with an upstanding arm 8- extendljngthereacrossthrough the upper portion of which is directed a supporting rod 9. Theextremities of the rod- 9 are engaged within the blocks 10 carried bythesid'e walls 11 or the casing. The corner portions of the member 6 areprovided with the upstanding arms 12 to the upper end portions of whichare pivotally connected at 5 as hereinbefore referred to the lower orouter extremitiesof the piston rods 1 coacting with thepist'ons2 workingwithin a pair of transversely aligned cylinders 1.

' The body member 6 of the turning cross' head C at one end thereof isprovidedwith a pair of depending and transversely aligned bearing lugs15 in which are keyed the extremitles of a shaft 16. Operatively engagedwith the shaft 16. is an end portion of apitman 17 the oppositeend'por'tio'n'of said pitman 17 being operatively engaged, as at'lS,with a cranl; 19 of a crank shaft'2Q. The end portion of the member 6 ofthe turning cross head 0 remote from the depending 111g 15 is providedwith a weight 14'to assure desired balance of the cross head C.

The block B supports a pair of cam shafts 21 coacting with the rods 22for operating in proper sequence the rocker arms 23 of the cylindervalves. The shafts 21 are in driven connection through the medium of theintermeshing gears 24and one of said shafts is in ion driyen connectionthrough the medium of the chain 25 or the like with the crank shaft 20.

In the accompanying drawings, the pistons 2 are disclosed as midwaytheir strokes and it is to be understood that a pair of transversel toaligned pistons operate in unison, thus e fecting requisite turning orswinging movement of the cross head C which, through the medium of thepitman 17, rotates the shaft 20. This mechanism is such as to eliminatedead J00 center and is one wherein full power is obtained during anentire stroke, thus eliminating vibration.

It is also to be noted that the structure as hereinbefore described, issuch to assure the pistons 2 traveling at all times along aperpendicular path, avoiding all piston slam and minimizing wear.

,From the foregoing description it is thought to be obvious that aninternal combustion engine constructed in accordance with my inventionis particularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification without departing from the principles and spirit thereofand for this reason I do not Wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin carrying out my invention in practice except as hereinafter claimed.

I claim In combination with a pair of vertically disposed cylinders,pistons working therein, a connecting rod pivotally connected to each ofsaid pistons and depending therefrom, a cross head mounted between thecylinders and within the crankcase, said cross head comprising a bodyportion, a central upstanding lug, a lug at the opposite end portions ofsaid body member, and a weight secured to said body member for balancingthe same, said central lug being pivotally mounted between thecylinders, and said end lugs being pivotally secured to the lower endportions of said connecting rods, a pair of depending lugs secured tosaid body portion of said cross head at a point spaced inwardly from oneend thereof, a pitman, a crankshaft, said pitman being pivotally mountedat one end to said depending lugs and at the opposite end to saidcrankshaft, a plurality of valves for each cylinder, and means foroperating said valves cooperatively with the turning of the crankshaft.

In testimony whereof I hereunto afiix my signature.

HARRY L. KLINE.
